There's someone else there

You are walking through the locker room to the shower when you notice a figure sitting across the room. It's a naked woman, looking away from you. She has mid length brunette hair. Her hand is moving around her crotch, but you can't see what she's doing. If you couldn't guess, the moan of pleasure she let out was a clue. You stand there, awkwardly watching, not sure what to do. You feel ashamed to watch this woman masturbate, but you are more than a little turned on. "Enjoying the show?" She calls out. She stands up, turns around and walks towards you. You watch in stunned awe. It's your P.E teacher Miss Summer, and she has an incredible body. She looks strong and lean, muscles ripple as she walks. Even her C-cup breasts seem pure muscle. What's really caught you eye is below though, as you look down you see she has a fully erect, 7 inch dick.

She walks very close to you, her dick is almost touching you. At 6ft 4inches tall she towers above you. You can't help but feel intimidated. "Like what you see?" she asks. "Ye-yes Miss" you stammer. She smiles and responds "I suppose this isn't what you were expecting when you were perving on me is it? and yes as you've probably figured out I was masturbating. But now you're here maybe I don't have to". "I wasn't perving...wait what do you mean?" You ask. Suddenly she grabs you by the shoulders and pushes you into the shower room. "What are you doing?!" you yell. "Shh, just go with it" she responds as she grabs you shirt and swiftly pulls your shirt off of you. You try to push her away as she holds you against the shower wall and removes your trousers and underwear. She grabs both your arms and pins you against the wall, leaning in close to you face. Her cock is pressed up against your stomach. "Don't even try to resist, you're going to love this" she whispers in your ear.
